A siphon spillway is designed to discharge 20 m3/sec with a head above the crest of hs, a crest elevation of 30 m, and an outlet elevation of 0 m. The allowable gauge pressure at the crest -8 m of water column during design flow. The crest section is followed in order by a vertical.: section, a 90° bend with centerline radius of curvature of 3 m, and a horizontal section at elevation 0 m. The distance from the entrance to the siphon crest is 3.2m, the vertical section is 30 m long, and the vertical section to outlet distance is 15 m. lf the siphon conduit has a Manning's coefficient n = 0.025 and the coefficients of entrance and of the bends (combined) are, respectively, Ke = 0. 5 and Kb = 0.3, what is the area of the siphon required to satisfy the given;: requirements?
